This reflective piece tells the story of how I started out doing Conversation Analysis (CA) and have been transitioning into mixed methods for some years now. My basic argument is that language learning talk too complex a phenomenon to analyse using single methodology. Specifically, it extremely difficult isolate from interaction concrete evidence specific individual items in terms change cogni...

We develop a class of mixed virtual volume methods for elliptic problems on polygonal/polyhedral grids. Unlike the element introduced in [22], [13], our are reduced to symmetric, positive definite primary variable without using Lagrangian multipliers. start from usual way changing given equation into system Darcy's law, u=−K∇p. By integrating equations with some judiciously chosen test spaces e...
